Kansas City Chiefs vs Philadelphia Eagles Betting Preview September 14th: Super Bowl Rematch

The Kansas City Chiefs return to Arrowhead Stadium in Week 2 for one of the most anticipated matchups of the NFL season — a Super Bowl LVII rematch with the Philadelphia Eagles. Oddsmakers have installed Kansas City as a +1.5 underdog (-110) with a +105 moneyline, a rare position for Andy Reid and Patrick Mahomes.

With the betting public leaning heavily on Philadelphia after their Week 1 win, this line presents strong value on the Chiefs in what sets up as both a revenge spot and a must-win game for the defending champions.

Why the Public Is Overvaluing Philadelphia

Casual bettors remember the Eagles controlling much of last year’s Super Bowl before Kansas City’s comeback. Pair that with a convincing Week 1 victory, and it’s easy to see why the public is lining up on Philadelphia.

What most don’t account for, however, is how much talent the Eagles lost in the offseason — particularly on defense, where multiple starters departed. This is not the same balanced roster that stormed through 2023. Their offense still has firepower, but the defense is more vulnerable, especially against elite quarterbacks.

Reid and Mahomes as Underdogs: A Rare, Profitable Spot

Here’s the betting angle that can’t be ignored: Andy Reid and Patrick Mahomes almost never enter games as underdogs — but when they do, they deliver.

• Mahomes is 9–1–1 ATS as an underdog in his career and has won the majority of those games outright.
• Reid’s history as an underdog goes back even further; he’s consistently been one of the league’s most profitable coaches to back when catching points thanks to preparation, scheming, and situational mastery.

Now combine that trend with the fact that Kansas City is an underdog at home, in Arrowhead — one of the most hostile environments in the NFL — and this line feels as though the wrong team is favored.

Why This Week 2 Spot Sets Up for KC

The Chiefs are coming off a narrow loss in Week 1, but that sets up a classic buy-low opportunity. Mahomes and Reid rarely lose consecutive games, and the offense is expected to find better rhythm at home after some opening-week hiccups.

This game also carries the revenge narrative from the Super Bowl, giving Kansas City extra motivation to flip the script in front of their home crowd.

Betting Outlook

• Spread: Chiefs +1.5 (-110)
• Moneyline: Chiefs +105
• Angle: Reid and Mahomes thrive when underestimated. With the public leaning Eagles and the Chiefs in a must-win spot, KC is the sharper play on both the spread and moneyline.

Final Thoughts

The Eagles are a public darling, but the loss of defensive talent — combined with Reid and Mahomes’ dominant record as underdogs — shifts value to Kansas City. Arrowhead will be rocking, and the Chiefs have both the historical trends and motivational edge on their side. At +1.5 and +105, the Chiefs are not just a live underdog — they’re the smart bet in this Week 2 Super Bowl rematch.
